数据库sys权限
查看哪个表被锁select b.owner,b.object_name,a.session_id,a.locked_modefrom v$locked_object a,dba_objects bwhere b.object_id = a.object_id;
查看是哪个session引起的select b.username,b.sid,b.serial#,logon_timefrom v$locked_object a,v$session bwhere a.session_id = b.sid order by b.logon_time;
查询Oracle正在执行的sql语句及执行该语句的用户SELECT b.sid oracleID, b.username , b.serial#, spid , paddr, sql_text , b.machine FROM v$process a, v$session b, v$sqlarea c WHERE a.addr = b.paddr AND b.sql_hash_value = c.hash_value ; select a.username, a.sid,b.SQL_TEXT, b.SQL_FULLTEXT from v$session a, v$sqlarea b where a.sql_address = b.address ;
查看正在执行sql的发起者的发放程SELECT OSUSER , PROGRAM , USERNAME , SCHEMANAME, B.Cpu_Time , STATUS, B.SQL_TEXT FROM V$SESSION A LEFT JOIN V$SQL B ON A.SQL_ADDRESS = B.ADDRESS AND A.SQL_HASH_VALUE = B.HASH_VALUE ORDER BY b.cpu_time DESC ;
查出oracle当前的被锁对象SELECT l.session_id sid, s.serial#, l.locked_mode , l.oracle_username , l.os_user_name , s.machine , s.terminal , o.object_name , s.logon_time FROM v$locked_object l, all_objects o, v$session s WHERE l.object_id = o.object_id AND l.session_id = s.sid ORDER BY sid, s.serial#;
kill掉当前的锁对象可以为alter system kill session 'sid,serial#';
